This species was originally known from one specimen from Hong Kong. It is now also known from 76 additional specimens from Vietnam, from a fish importer in Sweden. There is little published information on its biology and ecology, population status or impact of potential threats. It is therefore listed as Data Deficient.

Habitat and Ecology [top]

Habitat and Ecology:Species of Iniistius are called razorfish in allusion to their compressed bodies and the sharp leading edge of their forehead and snout, specialisations for quick entry into sand (Randall 2007).

Juveniles are found in coastal waters along reef edges on sand or rubble, or open patches on reef. Adults occur mainly in deep outer reef habitats in small loose group along sand ridges (Kuiter and Tonozuka 2001).
